在某些夜晚，天空是城里最好的表演。在这个夜晚，极光统治着天空，而造成这一彩色天空表演的地磁风暴源于日益活跃的太阳。令人惊讶的是，由于前一天接近的日冕物质抛射没有击中地球，所以预计这次风暴不会产生极光。在前景，两个惊喜的极光猎人凝视着惊人的和快速变化的天空。不管天气预报如何，极光不仅出现在遥远的北方，还出现在遥远的美国新墨西哥州。在芬兰北部拉普兰（Saariselkä）拍摄的广角照片中，可以看到明亮的极光，其细节程度、颜色范围和宽度都非常高。鲜艳的黄色、绿色、红色和紫色极光是由地球大气层中的氧原子和氮原子对入射电子的反应引起的。开放科学：浏览天体物理学源代码库中的3000多个代码

On some nights the sky is the best show in town. On this night, auroras ruled the sky, and the geomagnetic storm that created this colorful sky show originated from an increasingly active Sun. Surprisingly, since the approaching solar CME the day before had missed the Earth, it was not expected that this storm would create auroras. In the foreground, two happily surprised aurora hunters contemplate the amazing and rapidly changing sky. Regardless of forecasts, though, auroras were reported in the night skies of Earth not only in the far north, but as far south as New Mexico, USA. As captured in a wide-angle image above Saariselkä in northern Finnish Lapland, a bright aurora was visible with an unusually high degree of detail, range of colors, and breadth across the sky. The vivid yellow, green, red and purple auroral colors are caused by oxygen and nitrogen atoms high in Earth's atmosphere reacting to incoming electrons.
